Sun Mar 8 12:33:38 PST 1998 Jay Painter <jpaint@serv.net>
* gtk/gtkclist.c: the GList clist->selection now contains row indexes
in the data portion of the linked list structure instead of pointers,
fixed several bugs with the different selection modes
* gtk/testgtk.c: displays information for unselect events, and prints the list
of selected rows
Sun Mar 8 13:03:22 1998 Tim Janik <timj@gimp.org>
* gtk/gtkrange.h: removed gtk_range_calc_value().
